François GRANIER
I am a web penetration tester specialized in web intrusion testing, cyber exposure, and attack surface management. My expertise lies particularly in the client-side aspects of web security, focusing on browser behavior and browser fingerprinting—an area I am passionate about. I approach browser fingerprinting from an anti-bot and preventive perspective, aiming to identify user behaviors that indicate potential malicious activity. I enjoy collecting and correlating data to automate my processes as much as possible, enhancing both efficiency and detection capabilities.
Session
Web scraping continues to be a cornerstone of OSINT operations, particularly during Red Team engagements and external attack surface reconnaissance. Yet, as anti-bot technologies grow more sophisticated, traditional scraping methods based on direct HTTP requests are increasingly ineffective.
This talk takes a technical dive into browser-based scraping techniques that closely mimic real user behavior to evade detection, inspired by real-world mechanisms observed across major web platforms.
